At the bottom of the soles there are patches (demonstrated in photo no.2) of wavy silicone gel lines which are mould pressed on the tights (demonstrated in photo no.3), along with the company name (demonstrated in photo no.2).The thickness of the gel lines should be about 0.2mm. This part of the tights must be washable.

The tights must be black in colour, at a sheer 50 denier and the fabric should be a mixture of lycra and polyimide. Additionally they must include this type of grip at the top (demonstrated in photo no.1)

Thin layers of triangular foam cushion pads (demonstrated in photo no.4) inserted in each heel of the tights (demonstrated in photo no.5) to prevent friction occurring between the shoe and the skin. The pads must match the colour of the tights and should be sealed just like photo no.6; they should be almost unseen
